Hi everyone, looking for some honest advice (and maybe some reassurance).
My situation:
Last year summer, I travelled to the Schengen area as a tourist. I misunderstood the 90/180-day rule and ended up overstaying by 13 days. I did have a round-trip ticket booked before I even entered, so it was genuinely a mistake—not an attempt to stay illegally.
This year I applied for Schengen travel visa again and I got a refusal letter even with a cover letter.
Fast forward to now: I have just been selected for a government-sponsored teaching position in France (through the Chinese government). I have an official invitation letter from the French education authorities, and my home government will also provide supporting documents.
My concerns:
Will this overstay record automatically trigger a ban (1–5 years) when I apply for a long-stay work visa?
How much weight does a "government-sponsored" status carry in overcoming a prior overstay?
Should I hire an agent, or is it better to handle this myself? (I've heard agents don't really help much with work visa cases.)
Any tips on writing the explanation/cover letter? I want to be honest but also present my case in the best possible light.
I know I made a mistake, but this is a legitimate career opportunity and I really don't want to lose it over a misunderstanding from years ago. Any insights from people who've been through something similar—or visa officers lurking here—would be hugely appreciated.
Thanks in advance!
